pairwise_lmo outputs 0 update_direction #75

Closed GeoffNN closed 3 years ago

GeoffNN commented 3 years ago

This breaks the 'DR' step scheme, which is proportional to1/norm(update_direction). It happens even when we are not at the optimum.

In particular, where does this part of the code come from?

GeoffNN commented 3 years ago

This should be solved in the latest PR #83.
